Seismic vulnerability of continuous concrete bridges on different types of soil using fragility curves

One of the common methods for estimation of structural failures and earthquake damages is using fragility curves with probabilistic methods. In these methods, a structure such as a bridge can be classified into several structural types in terms of number of spans, type of connections, material used...
